Abstract

The utility model relates to an air throttle linkage regulating device for a mixed electric vehicle, wherein a pedal accelerator of an engine is connected with the upper end of an air throttle of the engine by a pull wire A; the lower end of the air throttle is connected with an engine casing by a spring C; a clutch is connected with a motor and the engine; a pull spring D is connected in series on the pull wire A for connecting the pedal accelerator and the air throttle; a separation arm of the clutch is connected with the air throttle by a pull wire B with proper length. The length of the pull wire B is when the clutch is in a separating state, the length of the pull wire B exactly causes the opening of the air throttle to be the minimal. The utility model enables the mixed electric vehicle to retain energy saving teamwork in running, and simultaneously the motor and the air throttle of the engine are controlled by the clutch; as the operating condition between the engine and the motor needs to be rationally adjusted, the engine always works in the optimal performance area and the running economy or the running power performance of the mixed electric vehicle is up to the optimal.

Description

A kind of hybrid electric vehicle throttle gate interlock control apparatus

Technical field:

The utility model relates to a kind of power control unit of hybrid electric vehicle, particularly engine throttle and throttle gate and clutch linkage control setup.

Background technology:

At present domestic existing automatically controlled mode is controlled the engine air throttle of hybrid electric vehicle, but used system is too complicated, the system that selects for use comprises a cover position servo motor and corresponding transmission device, and have one to overlap complicated control system, debugging is extremely inconvenient with maintenance, cost height not only, maintenance cost is also high.

Summary of the invention:

The purpose of this utility model is to overcome the above-mentioned drawback of existing hybrid electric vehicle throttle adjustment control setup, designs a kind of simple in structure, reliable operation, hybrid electric vehicle throttle adjustment device easy to maintenance.

Technical solution of the present utility model is a kind of hybrid electric vehicle throttle gate interlock control apparatus, it is connected with the throttle gate upper end of driving engine through backguy A by the foot throttle of driving engine, the throttle gate lower end is connected on the engine casing through spring C, power-transfer clutch connects electrical motor and driving engine, be serially connected with extension spring D on the backguy A that foot throttle connects with throttle gate, the separating arm of power-transfer clutch connects with throttle gate via the backguy B of a suitable length, backguy B length is: when power-transfer clutch was in released state, the length of backguy B just in time made the throttle opening minimum.

Description of drawings:

Fig. 1 is a hybrid electric vehicle throttle gate interlock control apparatus structural representation;

Fig. 2 is a hybrid electric vehicle throttle gate interlock control apparatus structure partial enlarged drawing;

The specific embodiment:

The utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing.

A kind of hybrid electric vehicle throttle gate interlock control apparatus, referring to accompanying drawing 1,2, it is that foot throttle 1 by driving engine 9 is attached to throttle gate 4 upper ends through backguy A2, extension spring D3, throttle gate 4 lower ends are attached on driving engine 9 casings by spring C5, throttle gate 4 lower ends are connected with the separating arm 7 of power-transfer clutch 11 by the backguy D6 of suitable length L in addition, power-transfer clutch 11 connects electrical motor 10 and driving engine 9, the length L of backguy D6 is: when power-transfer clutch was in released state, the length L of backguy B just in time made the aperture minimum of throttle gate 4.

Whether the utility model principle of work is: in parallel hybrid electric vehicle master mode, worked simultaneously by engine power and motor power and to realize line motorized motions or combination drive pattern; Driving engine when not working or running car power-transfer clutch when lower-speed state separate, this moment, the engine air throttle size should not change greatly with throttle, and motor speed is subjected to the throttle size and controls; Power-transfer clutch in conjunction with the time, should make engine air throttle and motor speed be subjected to throttle size control simultaneously, concrete mode of operation is as follows:

This device because disengaging of clutch arm 7 moves, drives engine air throttle 4 by backguy D6 and rotates when disengaging of clutch, makes engine air throttle 4 be in minimum aperture position.When foot throttle 1, drive backguy A2, backguy A2 elongates extension spring D3 distortion, and pulling force is less than the elastic force of spring C5, and throttle gate does not rotate, throttle opening can not followed acceleration cable and be rotated at this moment.When promptly realizing disengaging of clutch, throttle gate 4 aperture minimums, and also this moment, throttle gate 4 was failure to actuate, and made driving engine 9 be in idling.

This device when power-transfer clutch in conjunction with the time because disengaging of clutch arm 7 is return with cylinder, make backguy D6 no longer be subjected to the restriction of separating arm 7, throttle gate 4 can be changed with the size of throttle 1, thereby the rotating speed of driving engine is become with the throttle size.

Comprehensively described, when power-transfer clutch 11 separated, throttle 1 was not controlled the aperture of throttle gate 4, the spring D3 that just stretched, only power-transfer clutch 11 in conjunction with the time, throttle gate 4 just is subjected to the control of throttle 1, therefore disengaging of clutch during motor 10 independent drive vehicles, guarantees that driving engine is in idling mode.So not only reduce oil consumption but also reduced noise.

The utility model can make hybrid vehicle keep energy-conservation co-ordination under steam, pass through the clutch control electrical motor in the time of by foot throttle control engine air throttle, according to the working condition that need reasonably regulate between engine operating condition and the motor, driving engine is always operating in the optkmal characteristics zone, makes the economy of running car or dynamic property reach the best.

Claims

1, a kind of hybrid electric vehicle throttle gate interlock control apparatus, it is connected with the throttle gate upper end of driving engine through backguy A by the foot throttle of driving engine, the throttle gate lower end is connected on the engine casing through spring C, power-transfer clutch connects electrical motor and driving engine, be serially connected with extension spring D on the backguy A that it is characterized in that connecting with throttle gate with foot throttle, the separating arm of power-transfer clutch connects with throttle gate via the backguy B of a suitable length, backguy B length is: when power-transfer clutch was in released state, the length of backguy B just in time made the throttle opening minimum.
